Check digit calculator :
Check Digit :
The last digit of a bar code number is a computer Check Digit which makes sure the bar code is correctly composed.

GS1 Company Prefix (GCP) :
GCP is a part of the GS1 Identification number consisting of a GS1 Prefix and a Company Number, both of which are allocated by GS1 Organisations. GS1 India assigns GCP to its subscribers who administer the allocation of GS1 Identification numbers.

Item ID :
The GS1 subscribers allocate unique item ID for each item/product variant/ SKUs.

Check Digit calculation :
Check digit is calculated by using the digits present in GCP and Item ID parts of a GS1 identification number. This calculation, called the Modulo 10 algorithm, is same for all GS1 primary identification numbers.

Every time a computer decodes a GS1 barcode number it repeats the calculation and checks its answer against the check digit to verify the data integrity of the number.

Barcode Verification:
GS1 India offers a barcode verification service to enable comprehensive barcode diagnostics. This service helps organisations print and maintain bar codes that conform to ISO and GS1 specifications and ensures efficient scanning by any type of barcode scanner in a variety of scanning environments.

Verification should ideally be carried out at the artwork stage, prior to bulk printing and thereafter once in a year to ensure consistency in print quality in different print runs. Verification is carried out by an ISO compliant verifier, followed by additional minute observations on several criteria like print contrast, magnification, light margins, bar width, representation, check digit calculation, etc. keeping in mind GS1 specifications.

At the completion of testing, a bar code verification report is issued. Recommendations for changes, if necessary, are suggested in the report. GS1 verification reports are accepted by retailers globally and are even a pre-requisite for acceptance of products by many of them.

Benefits:
** GS1 India barcode verification service helps organisations:
** Get their products accepted by retailers worldwide
** Save costs of (a) reprinting due to bar code failures and (b) delay and possible order loss
** Retain company goodwill
